12-Bay Enterprise Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need high-capacity, centrally managed data infrastructure. It ships fully assembled and tested with twelve 12 TB enterprise hard drives providing 144 TB of raw capacity, 32 GB of DDR4 ECC memory, and an 800 GB dual-drive SSD cache. A 6-core Intel Xeon D-1726 processor drives file, virtualisation and surveillance workloads.

Suited For And Not Suited For

This unit suits IT teams deploying on-premises file services, backup targets or virtual-machine storage where redundant 10 GbE connectivity and hot-swap drive bays simplify maintenance. It is not suited for environments that require Fibre Channel or 25 GbE connectivity out of the box, nor for buyers who need GPU-accelerated compute or single-threaded performance beyond the Xeon D-1726 capabilities.

Build Integration

Dual redundant power supplies and 100-240 VAC input let the server plug into standard rack PDUs without special circuits. Two PCIe 4.0 x8 slots remain free for future network or cache upgrades, while two USB 3.2 Gen 1 ports support external backup or UPS signalling. The included out-of-band management LAN port enables remote hardware monitoring independent of the main network stack.

Questions about this item

What rack space and power connections do I need for the RS3626xs?

The 2U chassis measures 88 mm high by 482 mm wide by 724 mm deep and includes two C13-to-C14 cords for redundant supplies on 100-240 VAC 50/60 Hz circuits.

Can I keep using my existing 1 GbE switches with the two 10GbE RJ-45 ports?

Yes, the 10GbE ports auto-negotiate down to 1 GbE so current switches work, while Link Aggregation lets you combine both ports for extra throughput later.

How do I confirm the 800 GB cache and 144 TB array are active after first boot?

Open the web-based management console; the storage dashboard will show the two 400 GB cache modules and twelve 12 TB drives configured in the volume with healthy status indicators.
